Can I minify JSON that contains comments?

Standard JSON does not allow comments. Remove // or /* */ style comments first, or the parser will report an error.

Does minifying JSON break Unicode strings?

No. Minification only removes structural whitespace; string values including emoji and non-Latin scripts stay intact.

Yes. Change indent to 2 or 4 spaces to expand the same valid JSON into a readable layout.

Shipping JSON over the wire or storing logs often requires stripping spaces, newlines, and tabs without changing data values.

This page opens the formatter with compact (0-space) output selected so pasted JSON collapses to a single line after validation.

Use it before embedding JSON in environment variables, mobile bundles, or analytics pipelines—processing stays on your device.
